Geometry behind glass material appears slanted in render
It almost appears like it's index of refraction hitting the hard normals of triangulated geometry. Have you tried rendering with glass set to auto smooth (Object Data Properties>Normals>Auto Smooth)? Turn the glass object off during render and see if distortion occurs. Give the glass a shiny reflective MatCap material and check if normals reflect oddly. Some modifiers that can help (depending on if you want sharp or smooth glass): 1. Weighted Normal 2. Edge Split. You typically use them separately.
